Dear R-users,
I would like to know how expressions could be passed as arguments to
do.call functions. As illustrated in the short example below,
concatenating lists objects and an expression creates an expression
object, which is not an acceptable argument for do.call. Is there a way
to avoid that?
Thanks you
Sebastien
foo <- list(x=1:10, y=1:10)
mylist <- list(pch=6, col=2)
title <- "1 microgram"
title2 <- expression ("1 " mu "g")
do.call(plot, c(foo, mylist, main=title))
class(c(foo, mylist, main=title2))
do.call(plot, c(foo, mylist, main=title2))
